(1) That forum that he mentioned is probably the best, and most active, forum around to learn about genetic genealogy. I'm a regular participant on that forum, and it's a good mix of people who are experts in the field, and beginners who are simply trying to learn more about the field. It's a very friendly and helpful place for people to post questions, and you can feel confident that you'll get some authoritative replies.

(2) For those of you who have already tested the full 67 markers, a deep-clade test would be the next logical place to proceed. While the 67-marker test can help tell you about your relatively recent ancestors (within the past few centuries), the deep-clade test will determine (or confirm) your haplogroup very specifically, and that information can be used to help trace your deep ancestry (on the order of thousands, or tens of thousands, of years ago). That kind of thing could help tell us where the Gormans came from long before there were any such things as surnames, and from where our ancestors migrated into the British Isles.
